Hey bitcoin! I'm Lixin, longtime bitcoiner and creator of Cobo Vault.
I come from a background in the electronic hardware industry, and experienced one of my products being featured in Apple Stores around the world. Back in 2018 Cobo CEO Discus Fish, who also co-founded F2Pool, invited me to help build Cobo’s hardware product line. As we had strong ties to miners in China, we naturally designed the 1st gen with them in mind. In China, mining farms are nearly always built in very isolated places where there is very cheap wind or water electricity. When we built our 1st generation Cobo Vault hardware wallet, we needed to maximize the durability of the device in addition to its security. We used aerospace aluminum rather than plastic and made it completely IP68 waterproof, IK9 drop resistant, and military standard MIL-STD-810G durable for the mining industry.
Things changed last year when I went to Bitcoin 2019 and talked to lots of hodlers in the States. I found that 95% of them don’t care about durability. I asked them if they were afraid of their home being flooded or burned down in a fire. The answer is - yes, they are afraid of these things, but see them as very low possibilities. Even if something were to happen, they said they would just buy another HW wallet for 100 dollars. From these conversations, it became more and more clear we should design a product around a normal hodler’s needs.
Our 2nd gen product compromises on durability but doesn’t compromise on security.
Most hodlers share some needs with miners:
Aside from the legacy of the 1st gen, our 2nd gen product will have:

It’s effectively July 2017 in the world of decentralized finance (DeFi), and as in the heady days of the initial coin offering (ICO) boom, the numbers are only trending up.
According to DeFi Pulse, there is $1.9 billion in crypto assets locked in DeFi right now. According to the CoinDesk ICO Tracker, the ICO market started chugging past $1 billion in July 2017, just a few months before token sales started getting talked about on TV.
Debate juxtaposing these numbers if you like, but what no one can question is this: Crypto users are putting more and more value to work in DeFi applications, driven largely by the introduction of a whole new yield-generating pasture, Compound’s COMP governance token.
Governance tokens enable users to vote on the future of decentralized protocols, sure, but they also present fresh ways for DeFi founders to entice assets onto their platforms.
That said, it’s the crypto liquidity providers who are the stars of the present moment. They even have a meme-worthy name: yield farmers.
Where it startedEthereum-based credit market Compound started distributing its governance token, COMP, to the protocol’s users this past June 15. Demand for the token (heightened by the way its automatic distribution was structured) kicked off the present craze and moved Compound into the leading position in DeFi.
The hot new term in crypto is “yield farming,” a shorthand for clever strategies where putting crypto temporarily at the disposal of some startup’s application earns its owner more cryptocurrency.
Another term floating about is “liquidity mining.”
The buzz around these concepts has evolved into a low rumble as more and more people get interested.
The casual crypto observer who only pops into the market when activity heats up might be starting to get faint vibes that something is happening right now. Take our word for it: Yield farming is the source of those vibes.
But if all these terms (“DeFi,” “liquidity mining,” “yield farming”) are so much Greek to you, fear not. We’re here to catch you up. We’ll get into all of them.
We’re going to go from very basic to more advanced, so feel free to skip ahead.
What are tokens?Most CoinDesk readers probably know this, but just in case: Tokens are like the money video-game players earn while fighting monsters, money they can use to buy gear or weapons in the universe of their favorite game.
But with blockchains, tokens aren’t limited to only one massively multiplayer online money game. They can be earned in one and used in lots of others. They usually represent either ownership in something (like a piece of a Uniswap liquidity pool, which we will get into later) or access to some service. For example, in the Brave browser, ads can only be bought using basic attention token (BAT).
If tokens are worth money, then you can bank with them or at least do things that look very much like banking. Thus: decentralized finance.
Tokens proved to be the big use case for Ethereum, the second-biggest blockchain in the world. The term of art here is “ERC-20 tokens,” which refers to a software standard that allows token creators to write rules for them. Tokens can be used a few ways. Often, they are used as a form of money within a set of applications. So the idea for Kin was to create a token that web users could spend with each other at such tiny amounts that it would almost feel like they weren’t spending anything; that is, money for the internet.
Governance tokens are different. They are not like a token at a video-game arcade, as so many tokens were described in the past. They work more like certificates to serve in an ever-changing legislature in that they give holders the right to vote on changes to a protocol.
So on the platform that proved DeFi could fly, MakerDAO, holders of its governance token, MKR, vote almost every week on small changes to parameters that govern how much it costs to borrow and how much savers earn, and so on.

One thing all crypto tokens have in common, though, is they are tradable and they have a price. So, if tokens are worth money, then you can bank with them or at least do things that look very much like banking. Thus: decentralized finance.
What is DeFi?Fair question. For folks who tuned out for a bit in 2018, we used to call this “open finance.” That construction seems to have faded, though, and “DeFi” is the new lingo.
In case that doesn’t jog your memory, DeFi is all the things that let you play with money, and the only identification you need is a crypto wallet.
On the normal web, you can’t buy a blender without giving the site owner enough data to learn your whole life history. In DeFi, you can borrow money without anyone even asking for your name.
I can explain this but nothing really brings it home like trying one of these applications. If you have an Ethereum wallet that has even $20 worth of crypto in it, go do something on one of these products. Pop over to Uniswap and buy yourself some FUN (a token for gambling apps) or WBTC (wrapped bitcoin). Go to MakerDAO and create $5 worth of DAI (a stablecoin that tends to be worth $1) out of the digital ether. Go to Compound and borrow $10 in USDC.
(Notice the very small amounts I’m suggesting. The old crypto saying “don’t put in more than you can afford to lose” goes double for DeFi. This stuff is uber-complex and a lot can go wrong. These may be “savings” products but they’re not for your retirement savings.)
Immature and experimental though it may be, the technology’s implications are staggering. On the normal web, you can’t buy a blender without giving the site owner enough data to learn your whole life history. In DeFi, you can borrow money without anyone even asking for your name.
DeFi applications don’t worry about trusting you because they have the collateral you put up to back your debt (on Compound, for instance, a $10 debt will require around $20 in collateral).

If you do take this advice and try something, note that you can swap all these things back as soon as you’ve taken them out. Open the loan and close it 10 minutes later. It’s fine. Fair warning: It might cost you a tiny bit in fees, and the cost of using Ethereum itself right now is much higher than usual, in part due to this fresh new activity. But it’s nothing that should ruin a crypto user.
So what’s the point of borrowing for people who already have the money? Most people do it for some kind of trade. The most obvious example, to short a token (the act of profiting if its price falls). It’s also good for someone who wants to hold onto a token but still play the market.
Doesn’t running a bank take a lot of money up front?It does, and in DeFi that money is largely provided by strangers on the internet. That’s why the startups behind these decentralized banking applications come up with clever ways to attract HODLers with idle assets.
Liquidity is the chief concern of all these different products. That is: How much money do they have locked in their smart contracts?
“In some types of products, the product experience gets much better if you have liquidity. Instead of borrowing from VCs or debt investors, you borrow from your users,” said Electric Capital managing partner Avichal Garg.
Let’s take Uniswap as an example. Uniswap is an “automated market maker,” or AMM (another DeFi term of art). This means Uniswap is a robot on the internet that is always willing to buy and it’s also always willing to sell any cryptocurrency for which it has a market.
On Uniswap, there is at least one market pair for almost any token on Ethereum. Behind the scenes, this means Uniswap can make it look like it is making a direct trade for any two tokens, which makes it easy for users, but it’s all built around pools of two tokens. And all these market pairs work better with bigger pools.
Why do I keep hearing about ‘pools’?To illustrate why more money helps, let’s break down how Uniswap works.
Let’s say there was a market for USDC and DAI. These are two tokens (both stablecoins but with different mechanisms for retaining their value) that are meant to be worth $1 each all the time, and that generally tends to be true for both.
The price Uniswap shows for each token in any pooled market pair is based on the balance of each in the pool. So, simplifying this a lot for illustration’s sake, if someone were to set up a USDC/DAI pool, they should deposit equal amounts of both. In a pool with only 2 USDC and 2 DAI it would offer a price of 1 USDC for 1 DAI. But then imagine that someone put in 1 DAI and took out 1 USDC. Then the pool would have 1 USDC and 3 DAI. The pool would be very out of whack. A savvy investor could make an easy $0.50 profit by putting in 1 USDC and receiving 1.5 DAI. That’s a 50% arbitrage profit, and that’s the problem with limited liquidity.
(Incidentally, this is why Uniswap’s prices tend to be accurate, because traders watch it for small discrepancies from the wider market and trade them away for arbitrage profits very quickly.)

However, if there were 500,000 USDC and 500,000 DAI in the pool, a trade of 1 DAI for 1 USDC would have a negligible impact on the relative price. That’s why liquidity is helpful.
You can stick your assets on Compound and earn a little yield. But that’s not very creative. Users who look for angles to maximize that yield: those are the yield farmers.
Similar effects hold across DeFi, so markets want more liquidity. Uniswap solves this by charging a tiny fee on every trade. It does this by shaving off a little bit from each trade and leaving that in the pool (so one DAI would actually trade for 0.997 USDC, after the fee, growing the overall pool by 0.003 USDC). This benefits liquidity providers because when someone puts liquidity in the pool they own a share of the pool. If there has been lots of trading in that pool, it has earned a lot of fees, and the value of each share will grow.
And this brings us back to tokens.
Liquidity added to Uniswap is represented by a token, not an account. So there’s no ledger saying, “Bob owns 0.000000678% of the DAI/USDC pool.” Bob just has a token in his wallet. And Bob doesn’t have to keep that token. He could sell it. Or use it in another product. We’ll circle back to this, but it helps to explain why people like to talk about DeFi products as “money Legos.”
So how much money do people make by putting money into these products?It can be a lot more lucrative than putting money in a traditional bank, and that’s before startups started handing out governance tokens.
Compound is the current darling of this space, so let’s use it as an illustration. As of this writing, a person can put USDC into Compound and earn 2.72% on it. They can put tether (USDT) into it and earn 2.11%. Most U.S. bank accounts earn less than 0.1% these days, which is close enough to nothing.
However, there are some caveats. First, there’s a reason the interest rates are so much juicier: DeFi is a far riskier place to park your money. There’s no Federal Deposit Insurance Corporation (FDIC) protecting these funds. If there were a run on Compound, users could find themselves unable to withdraw their funds when they wanted.
Plus, the interest is quite variable. You don’t know what you’ll earn over the course of a year. USDC’s rate is high right now. It was low last week. Usually, it hovers somewhere in the 1% range.
Similarly, a user might get tempted by assets with more lucrative yields like USDT, which typically has a much higher interest rate than USDC. (Monday morning, the reverse was true, for unclear reasons; this is crypto, remember.) The trade-off here is USDT’s transparency about the real-world dollars it’s supposed to hold in a real-world bank is not nearly up to par with USDC’s. A difference in interest rates is often the market’s way of telling you the one instrument is viewed as dicier than another.
Users making big bets on these products turn to companies Opyn and Nexus Mutual to insure their positions because there’s no government protections in this nascent space – more on the ample risks later on.
So users can stick their assets in Compound or Uniswap and earn a little yield. But that’s not very creative. Users who look for angles to maximize that yield: those are the yield farmers.
OK, I already knew all of that. What is yield farming?Broadly, yield farming is any effort to put crypto assets to work and generate the most returns possible on those assets.
At the simplest level, a yield farmer might move assets around within Compound, constantly chasing whichever pool is offering the best APY from week to week. This might mean moving into riskier pools from time to time, but a yield farmer can handle risk.
“Farming opens up new price arbs [arbitrage] that can spill over to other protocols whose tokens are in the pool,” said Maya Zehavi, a blockchain consultant.
Because these positions are tokenized, though, they can go further.
This was a brand-new kind of yield on a deposit. In fact, it was a way to earn a yield on a loan. Who has ever heard of a borrower earning a return on a debt from their lender?
In a simple example, a yield farmer might put 100,000 USDT into Compound. They will get a token back for that stake, called cUSDT. Let’s say they get 100,000 cUSDT back (the formula on Compound is crazy so it’s not 1:1 like that but it doesn’t matter for our purposes here).
They can then take that cUSDT and put it into a liquidity pool that takes cUSDT on Balancer, an AMM that allows users to set up self-rebalancing crypto index funds. In normal times, this could earn a small amount more in transaction fees. This is the basic idea of yield farming. The user looks for edge cases in the system to eke out as much yield as they can across as many products as it will work on.
Right now, however, things are not normal, and they probably won’t be for a while.
Why is yield farming so hot right now?Because of liquidity mining. Liquidity mining supercharges yield farming.
Liquidity mining is when a yield farmer gets a new token as well as the usual return (that’s the “mining” part) in exchange for the farmer’s liquidity.
“The idea is that stimulating usage of the platform increases the value of the token, thereby creating a positive usage loop to attract users,” said Richard Ma of smart-contract auditor Quantstamp.
The yield farming examples above are only farming yield off the normal operations of different platforms. Supply liquidity to Compound or Uniswap and get a little cut of the business that runs over the protocols – very vanilla.
But Compound announced earlier this year it wanted to truly decentralize the product and it wanted to give a good amount of ownership to the people who made it popular by using it. That ownership would take the form of the COMP token.
Lest this sound too altruistic, keep in mind that the people who created it (the team and the investors) owned more than half of the equity. By giving away a healthy proportion to users, that was very likely to make it a much more popular place for lending. In turn, that would make everyone’s stake worth much more.
So, Compound announced this four-year period where the protocol would give out COMP tokens to users, a fixed amount every day until it was gone. These COMP tokens control the protocol, just as shareholders ultimately control publicly traded companies.
Every day, the Compound protocol looks at everyone who had lent money to the application and who had borrowed from it and gives them COMP proportional to their share of the day’s total business.
The results were very surprising, even to Compound’s biggest promoters.
COMP’s value will likely go down, and that’s why some investors are rushing to earn as much of it as they can right now.
This was a brand-new kind of yield on a deposit into Compound. In fact, it was a way to earn a yield on a loan, as well, which is very weird: Who has ever heard of a borrower earning a return on a debt from their lender?
COMP’s value has consistently been well over $200 since it started distributing on June 15. We did the math elsewhere but long story short: investors with fairly deep pockets can make a strong gain maximizing their daily returns in COMP. It is, in a way, free money.
It’s possible to lend to Compound, borrow from it, deposit what you borrowed and so on. This can be done multiple times and DeFi startup Instadapp even built a tool to make it as capital-efficient as possible.
“Yield farmers are extremely creative. They find ways to ‘stack’ yields and even earn multiple governance tokens at once,” said Spencer Noon of DTC Capital.
COMP’s value spike is a temporary situation. The COMP distribution will only last four years and then there won’t be any more. Further, most people agree that the high price now is driven by the low float (that is, how much COMP is actually free to trade on the market – it will never be this low again). So the value will probably gradually go down, and that’s why savvy investors are trying to earn as much as they can now.
Appealing to the speculative instincts of diehard crypto traders has proven to be a great way to increase liquidity on Compound. This fattens some pockets but also improves the user experience for all kinds of Compound users, including those who would use it whether they were going to earn COMP or not.
As usual in crypto, when entrepreneurs see something successful, they imitate it. Balancer was the next protocol to start distributing a governance token, BAL, to liquidity providers. Flash loan provider bZx has announced a plan. Ren, Curve and Synthetix also teamed up to promote a liquidity pool on Curve.
It is a fair bet many of the more well-known DeFi projects will announce some kind of coin that can be mined by providing liquidity.
The case to watch here is Uniswap versus Balancer. Balancer can do the same thing Uniswap does, but most users who want to do a quick token trade through their wallet use Uniswap. It will be interesting to see if Balancer’s BAL token convinces Uniswap’s liquidity providers to defect.
So far, though, more liquidity has gone into Uniswap since the BAL announcement, according to its data site. That said, even more has gone into Balancer.
Did liquidity mining start with COMP?No, but it was the most-used protocol with the most carefully designed liquidity mining scheme.
This point is debated but the origins of liquidity mining probably date back to Fcoin, a Chinese exchange that created a token in 2018 that rewarded people for making trades. You won’t believe what happened next! Just kidding, you will: People just started running bots to do pointless trades with themselves to earn the token.
Similarly, EOS is a blockchain where transactions are basically free, but since nothing is really free the absence of friction was an invitation for spam. Some malicious hacker who didn’t like EOS created a token called EIDOS on the network in late 2019. It rewarded people for tons of pointless transactions and somehow got an exchange listing.
These initiatives illustrated how quickly crypto users respond to incentives.
Read more: Compound Changes COMP Distribution Rules Following ‘Yield Farming’ Frenzy
Fcoin aside, liquidity mining as we now know it first showed up on Ethereum when the marketplace for synthetic tokens, Synthetix, announced in July 2019 an award in its SNX token for users who helped add liquidity to the sETH/ETH pool on Uniswap. By October, that was one of Uniswap’s biggest pools.
When Compound Labs, the company that launched the Compound protocol, decided to create COMP, the governance token, the firm took months designing just what kind of behavior it wanted and how to incentivize it. Even still, Compound Labs was surprised by the response. It led to unintended consequences such as crowding into a previously unpopular market (lending and borrowing BAT) in order to mine as much COMP as possible.
Just last week, 115 different COMP wallet addresses – senators in Compound’s ever-changing legislature – voted to change the distribution mechanism in hopes of spreading liquidity out across the markets again.
Is there DeFi for bitcoin?Yes, on Ethereum.
Nothing has beaten bitcoin over time for returns, but there’s one thing bitcoin can’t do on its own: create more bitcoin.
A smart trader can get in and out of bitcoin and dollars in a way that will earn them more bitcoin, but this is tedious and risky. It takes a certain kind of person.
DeFi, however, offers ways to grow one’s bitcoin holdings – though somewhat indirectly.
A long HODLer is happy to gain fresh BTC off their counterparty’s short-term win. That’s the game.
For example, a user can create a simulated bitcoin on Ethereum using BitGo’s WBTC system. They put BTC in and get the same amount back out in freshly minted WBTC. WBTC can be traded back for BTC at any time, so it tends to be worth the same as BTC.
Then the user can take that WBTC, stake it on Compound and earn a few percent each year in yield on their BTC. Odds are, the people who borrow that WBTC are probably doing it to short BTC (that is, they will sell it immediately, buy it back when the price goes down, close the loan and keep the difference).
A long HODLer is happy to gain fresh BTC off their counterparty’s short-term win. That’s the game.
How risky is it?Enough.
“DeFi, with the combination of an assortment of digital funds, automation of key processes, and more complex incentive structures that work across protocols – each with their own rapidly changing tech and governance practices – make for new types of security risks,” said Liz Steininger of Least Authority, a crypto security auditor. “Yet, despite these risks, the high yields are undeniably attractive to draw more users.”
We’ve seen big failures in DeFi products. MakerDAO had one so bad this year it’s called “Black Thursday.” There was also the exploit against flash loan provider bZx. These things do break and when they do money gets taken.
As this sector gets more robust, we could see token holders greenlighting more ways for investors to profit from DeFi niches.
Right now, the deal is too good for certain funds to resist, so they are moving a lot of money into these protocols to liquidity mine all the new governance tokens they can. But the funds – entities that pool the resources of typically well-to-do crypto investors – are also hedging. Nexus Mutual, a DeFi insurance provider of sorts, told CoinDesk it has maxed out its available coverage on these liquidity applications. Opyn, the trustless derivatives maker, created a way to short COMP, just in case this game comes to naught.
And weird things have arisen. For example, there’s currently more DAI on Compound than have been minted in the world. This makes sense once unpacked but it still feels dicey to everyone.
That said, distributing governance tokens might make things a lot less risky for startups, at least with regard to the money cops.
“Protocols distributing their tokens to the public, meaning that there’s a new secondary listing for SAFT tokens, [gives] plausible deniability from any security accusation,” Zehavi wrote. (The Simple Agreement for Future Tokens was a legal structure favored by many token issuers during the ICO craze.)
Whether a cryptocurrency is adequately decentralized has been a key feature of ICO settlements with the U.S. Securities and Exchange Commission (SEC).
What’s next for yield farming? (A prediction)COMP turned out to be a bit of a surprise to the DeFi world, in technical ways and others. It has inspired a wave of new thinking.
“Other projects are working on similar things,” said Nexus Mutual founder Hugh Karp. In fact, informed sources tell CoinDesk brand-new projects will launch with these models.
We might soon see more prosaic yield farming applications. For example, forms of profit-sharing that reward certain kinds of behavior.
Imagine if COMP holders decided, for example, that the protocol needed more people to put money in and leave it there longer. The community could create a proposal that shaved off a little of each token’s yield and paid that portion out only to the tokens that were older than six months. It probably wouldn’t be much, but an investor with the right time horizon and risk profile might take it into consideration before making a withdrawal.
(There are precedents for this in traditional finance: A 10-year Treasury bond normally yields more than a one-month T-bill even though they’re both backed by the full faith and credit of Uncle Sam, a 12-month certificate of deposit pays higher interest than a checking account at the same bank, and so on.)
As this sector gets more robust, its architects will come up with ever more robust ways to optimize liquidity incentives in increasingly refined ways. We could see token holders greenlighting more ways for investors to profit from DeFi niches.
Questions abound for this nascent industry: What will MakerDAO do to restore its spot as the king of DeFi? Will Uniswap join the liquidity mining trend? Will anyone stick all these governance tokens into a decentralized autonomous organization (DAO)? Or would that be a yield farmers co-op?
Whatever happens, crypto’s yield farmers will keep moving fast. Some fresh fields may open and some may soon bear much less luscious fruit.
But that’s the nice thing about farming in DeFi: It is very easy to switch fields.

Cryptocurrencies are about a major contribution to the transformation of the existing financial system. They can dramatically change the world and be of great benefit to humankind. But looking for benefits mustn't do harm to the environment.
We've taken up this theme for a reason. It is indeed possible to do harm. In fact, harm is already being done. Do you want to know in what way? By traditional mining, which is necessary to maintain the Bitcoin network, and thousands of other Proof-of-Work-based cryptocurrencies.
Negative impact of traditional mining
In order to maintain the Bitcoin network or other PoW-based cryptocurrencies, miners have to solve complex computational math problems — by doing so they verify the authenticity of transactions and add valid ones to the blockchain. This process is dubbed mining and requires extensive computing resources.
The need to compete to solve a mathematical puzzle and receive a reward makes people use more and more powerful equipment. This is how new bitcoins are generated. With the cryptocurrency boom, harmless mining on computers turned into an endless race among miners. Today miners not only buy high-performance computers. Some miners create farms consisting of energy-consuming ASIC devices while others use huge plants to mine bitcoins.
A mining farm consisting of thousands of ASIC devices. Source.
As you know, intensive computing power requires elevated power expenses and leads to air pollution and a waste of natural resources. This poses a serious problem. Nowadays electric power stations, which are thermal power plants (TPP), burn fossil fuel, such as coal or natural gas, to produce electricity.
This process causes CO2 (carbon dioxide) emissions which adversely affect the biosphere — mining contributes to the greenhouse effect which heats the planet up. This consequently causes a global warming effect with its associated impacts on the environment and may pose threats to life on the planet. What is more, every minute we are breathing the same polluted air, thereby being at risk of a bunch of diseases and complications. All these factors shorten life expectancy for us and our children. Air pollution cause a great deal of premature deaths
The more carbon dioxide gets into the environment, the more harm it does. Carbon dioxide is a harmful by-product of industrial activity. The biting irony is that we use natural resources to generate these emissions, and these resources have limits too. Traditional mining significantly exacerbates the global problem and the situation has been deteriorating in recent years.
The effects of carbon footprint are already being felt
There are, undoubtedly, a lot of other factors that cause global environmental degradation, but the impact of mining should never be ignored. Bitcoin mining is estimated to produce as much carbon dioxide as that produced by industries of Estonia, Switzerland, the Czech Republic, Jordan, or Sri Lanka.
The entire bitcoin network is responsible for 22-22.9 million tons of CO2 per year — just think and try to imagine how much it is. Chinese miners represent about half (47%) of emissions. In China energy is cheap as it's produced by coal-fired thermal power plants. Once we add emissions produced by mining other cryptos, the numbers will double!
Powerful mining equipment. Source.
Two years ago, Nature Research journal published an article regarding Bitcoin emissions. It said: "We cannot predict the future of Bitcoin, but projected Bitcoin usage, should it follow the rate of adoption of other broadly adopted technologies, could alone produce enough CO2 emissions to push warming above 2 °C within less than three decades." Two years later, we can see the researchers' concerns had the ground — digital gold keeps to be mined with the same enthusiasm as well as the planet keeps to be polluted. "It [Bitcoin] alone could produce enough emissions to raise global temperatures as soon as 2033, " warn a group of researchers.
As an alternate solution, miners are encouraged to use renewable energy (wind, solar, etc.) — which can make bitcoin mining more environmentally friendly. Unfortunately, renewable energy sources account for just a small share of global energy which makes them impossible to be used widely. Moreover, in the pursuit of profit, miners don't seem particularly eager to get rid of profitable equipment which cost them a fortune.
Nonetheless, the fact that modern cryptocurrencies disapprove environment-damaging mining lets us hope for the early improvement of the situation. UMI is one of these cryptocurrencies.
UMI is a green cryptocurrency based on smart contract
Not all cryptocurrencies use computing power to generate new coins. For example, there are cryptocurrencies based on Proof-of-Stake (PoS) and Proof-of-Authority (PoA) technology. UMI is just like that.
As a substitute for mining and to incite users, UMI uses Staking Smart Contract which allows generating new coins with no energy expenses and powerful equipment. No waste of natural resources. Staking technology is perfectly safe for the planet. This is the latest technological development loop of crypto industry.
UMI can be definitely called an environmentally friendly cryptocurrency as it has no negative impact on the environment. Today this is of greatest importance for all of us. UMI staking neither endangers human health nor harms the environment. In other words, we are protecting the planet and all the people that inhabit it. This is something we can be really proud of. Because the environment influences our health, and good health is the most important thing in life.
As a final note, we would like to say that adhering closely to their ideology, the UMI team collaborates only with environmentally conscious partners who are concerned with the protection of the natural world. This was the main reason for choosing the ROY Club as our partner. We are certain this will be productive cooperation which will make this world a better place.
Join in and invite all your friends — together we can create new UMI coins using eco-friendly staking and care for our planet!
Best regards, UMI Team!

Since the creation of Bitcoin (BTC) in 2009, there have been no severe geomagnetic storms. However, Bitcoin (BTC) users are highly dependent on internet and electricity, and it is inevitable that one day, a severe geomagnetic storm will disrupt Bitcoin (BTC) users across the globe.
A geomagnetic storm starts at the surface of the sun, where massive helical loops of magnetic energy extend outwards into space. These helical magnetic fields often break down in a phenomenon known as magnetic reconnection, and this projects a tremendous amount of radiation and charged particles into space. This is called a solar flare and coronal mass ejection.
When solar flares hit the Earth, they cause rapid fluctuations in Earth’s magnetic field. A fluctuating magnetic field induces electrical currents in conductors. The world’s internet is connected with cables that span the entire ocean, and these cables are highly susceptible to induced electric currents from a geomagnetic storm. Further, electrical power lines extend across great distances on land, and during a severe geomagnetic storm, the current would become so great that transformers would explode and power substations could catch fire.
In March 1989 a severe geomagnetic storm caused Quebec’s power grid to go down within seconds, and another storm in August 1989 halted trading on the Toronto Stock Exchange. However, these events do not compare to the Carrington Event of 1859, the largest geomagnetic storm in recorded human history. Telegraphs system across the world were overloaded with induced electrical current, causing pylons to spark and operators to get shocked. After electricity was cut from the grid numerous telegraph operators were still able to send messages since the geomagnetic storm was generating electricity in the lines. Aurora Borealis, an atmospheric phenomena typically only observed in polar regions, was observed as far south as Cuba and Hawaii.
If the Carrington Event were to occur today, it would shut down electrical and communication grids for days, months, even years, and ultimately, damage could be trillions of dollars. In 2012, a Carrington-sized solar flare happened, but it missed Earth.
The Bitcoin network has just over 10,000 full nodes as of this writing, mostly centered in the United States, Europe, China, and Japan. Unfortunately these nodes are far enough from the equator that they would be highly susceptible to a severe geomagnetic storm and would likely go offline.
Maintaining Bitcoin nodes in the tropics, especially right around the equator, will be crucial to the survival of the Bitcoin network during a severe geomagnetic storm. Even in the worst geomagnetic storm, the equatorial region will be shielded by Earth’s magnetic field, and nations right on the equator may experience little disruption to their electricity and internet.
At this time, there are only about 50 Bitcoin nodes in the equatorial region, mostly in Malaysia, Venezuela, and Colombia. In order for the Bitcoin network to be robust in the event of the most catastrophic geomagnetic storm, global efforts should be made to increase the number of Bitcoin nodes and mining farms along the equator.
Bitcoin users at higher latitudes, like the United States, can take steps to prepare for a geomagnetic storm. All Bitcoin and cryptocurrency should be held in personal wallets where the private key is exclusively controlled by the user, since even reputable wallet services could have their servers fried during a severe geomagnetic storm.
Also, having a personal source of renewable electricity like wind, solar, or hydroelectric could ensure that Bitcoin users keep their electricity running even when the whole grid collapses.
Bitcoin users and miners should disconnect their computers and rigs from electricity before the geomagnetic storm hits. For the most severe geomagnetic storms — ones like the Carrington Event — there is less than one day of warning. Bitcoin users can monitor the Space Weather Prediction Center (SWPC) to avoid being caught off-guard. Computers and mining rigs connected to electricity during a geomagnetic storm could get fried by the induced electrical current.
Maintaining an internet connection is the hardest thing to prepare for. Not even satellite internet is a good option, nor the Blockstream satellites which broadcast the Bitcoin blockchain from space, since satellites can easily get fried by radiation during a severe geomagnetic storm. The best thing Bitcoin users could do is make sure they control their private keys, have a personal renewable electricity source, protect their computer from the storm, and wait for electricity to come back up.
A bitcoin mining farm caught fire last week due to what some suggest was faulty wiring and bad power supply units (PSUs). The industrial mining farm appears to be four floors high and seems to be located in Inner Mongolia. Initial suggestions were that this belongs to Innosilicon, the biggest mining manufacturer after Bitmain. Innosilicon however has categorically denied it, stating: “In the ...

Ouch, Crypto Mine on Fire While Bitcoin is a digital coin, it has a physical component: nodes and miners. A network of tens of thousands of mining machines constantly process transactions and place them into blocks, creating a chain. Due to their physicality, these machines are susceptible to risk. A “mega farm” recently found this out the hard way. Bitcoin mining mega farm burns down, destroying $10m Bitcoin mining mega farm burns down in China, destroying $10m of cryptocurrency machines. Video appears to show fire ravaging Innosilicon's ... A fire in a warehouse-style facility in Thailand has destroyed hundreds of bitcoin mining rigs, whose value may run into the millions of dollars, according to accounts on foreign press and social networks. Rich Miller Nov 06, 2014. Reports of a fire in a warehouse-style facility in Thailand have raised tough questions about the wisdom of hosting expensive bitcoin mining equipment in low-cost ...
